Ultrasonic Bark Control Devices emit an ultrasonic tone that only dogs can hear. The device detects excessive barking and activates. This results in a safe ultrasonic sound that is audible to dogs, but not to humans. Your dog hears the sound and will stop barking. Safe and effective for all breeds and sizes of dogs.

Tabletop or free-standing ultrasonic deterrents stop your dog's excessive barking. When your dog barks, the collarless unit emits an annoying high-pitched sound that discourages your dog from barking. The indoor unit works on all dogs inside your home within 25 feet. The outdoor units work on all dogs outside within 50 feet.

How It Works:

When your dog barks, a microphone in the bark deterrent picks up the sound and sends an ultra-high frequency sound to interrupt your dog’s bark, without hurting his sensitive ears. The tone is annoying but harmless and inaudible to most people. It works on all dogs within hearing range.
